Also known as Vagrania-Thliborhynchia Community
Where: Yukon, Canada (65.0° N, 135.0° W: paleocoordinates 0.1° S, 41.5° W)
• coordinate estimated from map
• local area-level geographic resolution
When: Road River Group, Pragian (410.8 - 407.6 Ma)
• Pragian (140-260 m of section 1 and 250-360 m of section 2).
Environment/lithology: slope; carbonate and siliciclastic
•"This community is everywhere typically found in deep water, basin-slope deposits. Debris flows are common, and gbraded beds may be present. A relatively deep and quiet water setting is proposed...Probably intergrades with the slightly shallower (BA 3) Atrypa-Gypidula community."
•SEP environmental call based on given info. and regional context
Collection methods: "Bulk faunal composition." Brachiopods are assigned to five abundance categories.
